To all whom it may concern: I

Be it known that I, WLADYSLAW Wnonam.

GZYK, e eer, a subject of the Emperorof Austriaungary, residing at Borislaw, Galicia, Austria-Hungary, have inventednew and useful Im rovements in and Relating to Deep-Boring pparatus, of which the following 1s a specification.

M invention relates to boring'apparatus, partlcularly for veryx deep borin purposes, in which the boring-c ain 1s direct connected to the sprin s. The object of t is to adjust the tenslon of the springs to the' strain on the chain caused at any moment by the va ing load'on or resistance to the boring-r0. s.- As is well known, these springs, used to compensate for excessive and constantly-Va g strains and to prevent breaking1 of the .0 amor damage to the b0 -.rods, ave hitherto been arran ed on the eep-boringbeam's in such way t t the action of the sprin unfavorably affected by the beam or hmited by the driving device.

In'order to make the pendent of the rest of the apparatus, t M ey-are arranged accord' to the present invention either on the framing or on the beam, being, on the one hand, connected with the latter or with the frame and, on the other hand, engaging directly or by means of a rocking frame- ,lever with the boring-chain. This frame-la ver is used for guiding the chain by means of rollers to the unwinding device on the frame of the crane apparatus. The unwindin deviceor winch can, however, be arrange directly on the frame-lever, so that it is inserted between the springs and the chain, and thus: can oscillate'with the frame-lever under the influence of the action of the s rings and chain. The dri of the beam is e ected by means I ofa crank- 'sk with an adjustable crank-pin,

by means of which the stroke-of the boringtool can be increased or-reduced, as maybe I desired. I i Figure 1 1s a .view 1n side elevation, partly in section, of one form ofthe a paratus. Fig;

Fig. 7 is a sectional view of said disk, taken coincident with a line joinirlig the centers'otits shaft 26 and pivot 29; 1g.1 8.is ayiew, partly 1n side elevation and partly in section, of still another form of the apparatus; and Fig. 9 is a view in end elevation of the apparatus shown in Fig.

ally mounted on the rocking spindlel of the beam 2, a spring 4 engagin withthe upper end of the'said frame-lever, t e casing 5 serv- ,a's-abutment for the 'said spring, beiIIig n more particularmthe case of deep boring, there is provide a number of volute springs 4, arranged one behind another, which can be brought to the desired state of tension when- Y ever retiluiredi Such an arrangement of the springs entirelin'de-i springs as the further advantage that in the event of one spring breakingronly that spring need be replaced. On the aims is arran e whichsupplies the 'orin -',tool chain 18 from the" drum arrangedgon t e s indle 8. The chain thence passes over a rol er 21, mounted on the rockin spindle 1 of the beam, round a roller 22 exit ebeam 2 to a roller 23 in the pivotedlever 3, and thence about rollers 11 and 10 to the beam-head 12. The osition of the roller-23 on the lever-arm 3, re atively to the pivot 1 may be varied tov allow for difier-.

ent-degrees of tension on the Wheninworldng the boring-tool is iraised, the lever-31s s pressed, and at the same time the chain 18,

owin to its guidance onthe lever, 33, can follow. t e

(owin tor..the-. "large number of spr ngs 'arran e v onebehind another) to obtain an elastic s 'ock even when the load on the chain and rods is ve great after the boring work has great] a vanced.

In oring apparatus of less strong conforward 'bygthe weight ofp I A the boring-rods, it esprings 4Jbei ng com handle 19, arranged on the same spindle.

struction it is possible to arran e the unwinding-winch 6 7, Figs. 4 and 5, ectly on the pivoted lever, in which case it artioipates in the oscillation of the latter. The operation of the winch for unwinding the chain as the boring advances and when necessary for raisinglt e boring-tool is eifected from below e1t er by means of a chain-wheel 14, mounted on the spindle 13 of a worm 6, with the assistanceof a chain, or by means of a cranic- 11 order, however, to enable the boring-chain when without any load to be quickl raised, the hub of the non-keyedworm-w eel 7 is formed as one-half of a clutch-coupling, the other cou ling-half 20, Fig. 5, being longitudinally a justable on the spindle 8 of the worm-wheel, so that it can be secured in the desired position. The s indle 8 can therefore be cou led by the c utch to the wormear or ma e to-rotate independently of the atter by uncouplin the clutch, so that the chain can be quicl y wound on the drum mounted on the spindle by turning a crankhandle 15 on the spindle.

Another modification of the above boring apparatus (shown in Figs. 8 and 9) consists in the pivoted lever with the unwindingwinch being arranged on the framin preferably between the supports for the cam, in which case the spring 4 engages at one end with the lever 3' and is secured at its other end to the framing, the chain 18 being uided from the drum over the roller 21 of the camspindle 1 to the beam head 12. This arran ement has the im ortant advantage of faci itating the manipu ation of the unwinding-winch and of making the latter, as well as the springs, more easily accessible. The chain-dotted lines in Figs. 8 and 9 show a plan of direct connection of the chain 18 with the sprin To that end the chain is guided from the beam-head 12 over the roller 21 to a roller 34, connected with the spring, and

thence to the unwinding-winch, so that. the chain is acted upon directly by the spring. The beam is provided at one end with a curved head 16, which, as is well known, serves to insure correct guiding of the chain in axial direction of the boring-hole in any position of the beam. From this head the chain is not, however, guided in a straight line to the unwinding winch, as hitherto, but is caused to follow a sinuous path in the head by a windingchainway 17, arranged above the part 16, and by the rollers 10 and 11. The object of this arrangement is, on the one hand, to prevent the chain from jumping off the ids when the boring-tool is thrown back and ,the chain suddenl springs upward and, on the other ha to facilitate smooth movement of the chain without great friction. The rocking of the beam is efiect- ,rocking eraser or recesses 27, arranged in a circle round the disk. In the center of this circle is pivoted about a pin 29 an arm 28, provided with the crankin 30, to which the connecting-rod is secure and which can be secured in any desired position in the circle by means of screws, bolts 31, or the like introduced into the holes 27. The second attachment of the arm 28 is constituted by it's pivot 29,- which to that end is tapered and can be tightened b means of a nut 32. The distance of the" ho cs 27 from the driving-shaft varies, so that by securing the arm 28 to one or other of the holes 27 the distance between the crank-pin 30 and the drivmg-shaft 26 can be altered, thereby obtaining a variable crank-throw within certain limits.

An im ortant advantage of the crank-disk described consists in the quick and easy Shifting of the arm 28 and in the reliability with which it retains a position once given to it. In order to simplify and to facilitate still more the shiftin of the crank-pin, there are provided on t e arm 28 round the in 29 setscrews 33, whereby by screwing t em in-the conical pin 29 can be easily forced out should it have ecome jammed.
